arm: Fix compile warning for psci

2014-05-27T13:58:49+00:00

Commit e71246a23acbc89e9cb4ebf1558d60e65733479f changes psci_init from a function returning a void to an int, but does not change the non CONFIG_ARM_PSCI implementation to return a value, which causes a compile warning. Just return 0. Cc: Ashwin Chaugule Cc: Shawn Guo Signed-off-by: Christoffer Dall Signed-off-by: Paolo Bonzini

PSCI: Add initial support for PSCIv0.2 functions

2014-05-15T14:16:00+00:00

The PSCIv0.2 spec defines standard values of function IDs and introduces a few new functions. Detect version of PSCI and appropriately select the right PSCI functions. Signed-off-by: Ashwin Chaugule Reviewed-by: Rob Herring Acked-by: Catalin Marinas

arm: introduce psci_smp_ops

2013-05-21T14:24:11+00:00

Rename virt_smp_ops to psci_smp_ops and move them to arch/arm/kernel/psci_smp.c. Remove mach-virt/platsmp.c, now unused. Compile psci_smp if CONFIG_ARM_PSCI and CONFIG_SMP. Add a cpu_die smp_op based on psci_ops.cpu_off. Initialize PSCI before setting smp_ops in setup_arch. If PSCI is available on the platform, prefer psci_smp_ops over the platform smp_ops.
